Disclosed herein, in certain embodiments, are vacuum-based systems, products, devices, and methods for de-odorizing, disinfecting, or cleaning articles such as clothing, shoes, toys, or dishes. A system or device can comprise a vacuum chamber comprising an housing defining an internal space having an internal pressure and an opening; a vacuum lid adapted to engage with the opening of the vacuum chamber; and a vacuum source connected to the vacuum chamber, wherein operation of the vacuum source reduces the internal pressure of the internal space of the vacuum chamber, wherein the lower internal pressure enhances the vaporization and removal of odors located on one or more articles disposed within the vacuum chamber.

A washing machine includes: a frame, a drum receiving laundry, a washing chamber including (i) a first housing defining an opening and a space into which the drum is inserted, (ii) a barrier surrounding the opening and coupled to the first housing, and (iii) a second housing surrounding a first surface of the barrier and coupled to the first housing, a storage tank receiving carbon dioxide to be supplied to the drum, a distillation chamber separating contaminants dissolved in liquid carbon dioxide, an electronic circuit, and a configuration unit. The configuration unit includes a pipe moving the carbon dioxide, a first compressor and a second compressor compressing the carbon dioxide discharged after washing is completed in the drum and moving the compressed carbon dioxide into the storage tank, and an oil separator separating oil from the carbon dioxide compressed in the first compressor and the second compressor.

A washing machine is configured to perform washing using carbon dioxide. The washing machine includes a first housing that defines an opening and an inner space, a drum disposed in the inner space of the first housing and configured to receive laundry, a barrier that is coupled to the first housing and seals the opening of the first housing, and a second housing that faces a surface of the barrier and is coupled to the first housing. The barrier defines (i) a first space between the first housing and the barrier from leaking and (ii) a second space between the second housing, where the barrier is configured to block liquid carbon dioxide injected into the first space from leaking into the second space.

A laundry treating apparatus includes a pressure vessel configured to receive fluid and to maintain a pressure therein to be higher than an atmospheric pressure, a separator that divides the pressure vessel into a first chamber and a second chamber, a drum rotatably disposed in the first chamber and configured to accommodate laundry therein, a driver configured to rotate the drum, and a pump configured to cause the fluid to flow between the first chamber and the second chamber.

Disclosed herein, in certain embodiments, are vacuum-based systems, products, devices, and methods for de-odorizing, disinfecting, or cleaning articles such as clothing, shoes, toys, or dishes. A system or device can comprise a vacuum chamber comprising a housing defining an internal space having an internal pressure and an opening; a vacuum lid adapted to engage with the opening of the vacuum chamber; and a vacuum source connected to the vacuum chamber, wherein operation of the vacuum source reduces the internal pressure of the internal space of the vacuum chamber, wherein the lower internal pressure enhances the vaporization and removal of odors located on one or more articles disposed within the vacuum chamber.

A laundry composition according to the present disclosure includes a solvent selected from the group consisting of solketal and derivatives thereof and a fragrance, wherein the fragrance has a log P value of −1.0 to 4.5, and a washing machine includes a washing unit configured to receive a solvent to wash accommodated fibers; a steam collector configured to condense a gaseous phase discharged from the washing unit and supply the same to a solvent collector; and the solvent collector configured to collect a liquid phase discharged from the washing unit and supply the solvent to a solvent supplier, wherein the solvent collector includes a filter unit configured to remove foreign substances from the solvent supplied from at least one of the steam collector and the washing unit; and a solvent storage configured to store the solvent supplied from the filter unit.

An ionic oxidation refreshing system for refreshing an odorized item, comprising an enclosure with an airflow system to contact the odorized item on all sides; an ionization system that produces a positively charged ionized ozone gas mixture inside of the enclosure, killing germs, including odor-causing bacteria, viruses, molds, and fungus, and provides the odorized item inside the enclosure with a net positive charge; a filter that neutralizes and filters out any toxic by-products; an electrostatic liquid atomization system that creates a fine mist of a quick-cleaning solution, and, in conjunction with the airflow system, causes solution droplets to penetrate deep into the odorized item and agitate a surface of the odorized item, ensuring the formula is evenly delivered onto the odorized item without over saturating any area.

Disclosed herein, in certain embodiments, are vacuum-based systems, products, devices, and methods for de-odorizing, disinfecting, or cleaning articles such as clothing, shoes, toys, or dishes. A system or device can comprise a vacuum chamber comprising an housing defining an internal space having an internal pressure and an opening; a vacuum lid adapted to engage with the opening of the vacuum chamber; and a vacuum source connected to the vacuum chamber, wherein operation of the vacuum source reduces the internal pressure of the internal space of the vacuum chamber, wherein the lower internal pressure enhances the vaporization and removal of odors located on one or more articles disposed within the vacuum chamber.

A novel filter canister configured to dock into a dry-cleaning machine incorporates unique structural elements that reduce or eliminate debris overfill and jamming of the filter canister after an extended dry-cleaning operation. In particular, a novel perforated hollow inner core, a vertical strut-based canister docking frame, a washable and reusable cartridge with a perforated rigid inner surface layer and a particulate filtering element-encapsulating outer surface layer, and a removable lid that secures or frees the washable and reusable cartridge that constitute the novel filter canister enable a dry-cleaning operator to install, clean, and reuse the washable and reusable cartridge conveniently for numerous dry-cleaning cycles while avoiding debris overfill, canister jamming, and frequent filter canister replacement and repurchase needs that are endemic in conventional dry cleaner filter designs that tend to be cumbersome, costly, and environmentally detrimental.
